Diaper studies/testing

I am looking to share experiences with others who have taken part in diaper studies either as a child or an adult. Has anyone here done such a thing and is willing to share their experience?

No I haven't but if you hear of any such studies in the US please let us know.

Not heard of anything like that either; but how cool would that be to be involved in diaper studies. Someone wanting your opinion on what we think of a diaper and maybe even getting paid to wear diapers. That would be awesome.
